Description
EX3C3 120kVA Three-Phase Online UPS
The DAXIN ENERGY EX3C3 120kVA online UPS is designed for critical power backup applications that require stable, clean and continuous three-phase power. It uses a double-conversion online topology to protect sensitive equipment from grid fluctuation, voltage instability, frequency variation, noise interference and power interruption.
Key Features
High-Reliability Double-Conversion Design
- True online double-conversion topology provides stable sine wave output.
- Output frequency tracking, phase locking, voltage regulation and noise filtering help protect critical loads.
- Advanced modular dual-CPU control improves system reliability and operating stability.
- Wide AC input voltage range of 380VAC ±25% reduces unnecessary battery discharge in unstable power environments.
- DC start function allows the UPS to start directly from battery when utility power is unavailable.
High Efficiency and Low Grid Interference
- Advanced PFC power factor correction technology keeps the input power factor close to 1.
- Input harmonic filters comply with international power quality requirements and reduce feedback pollution to the grid.
- Input and output harmonic filtering minimizes UPS interference with the utility power system.
- High-frequency filtering and synchronization technology improves generator compatibility.
Complete System Protection
- Output overload protection.
- Output short-circuit protection.
- Inverter over-temperature protection.
- Battery low-voltage warning protection.
- Battery overcharge protection.
- Manual maintenance bypass switch supports easier service without interrupting load power.
Intelligent Monitoring and Management
- LCD display shows UPS operating status, parameters and alarm information in real time.
- RS232 / RS485 communication interfaces support local monitoring.
- Optional SNMP network adapter enables remote UPS management.
- Compatible with intelligent UPS monitoring software for centralized power management.
Optional Intelligent Battery Monitoring
- Supports single battery detection.
- Provides over-voltage, under-voltage and voltage difference alarm functions.
- Battery fault information can be displayed on the screen to notify administrators quickly.
Strong Environmental Adaptability
The circuit boards are installed in a fully enclosed structure and treated with conformal coating, making the UPS more suitable for harsh environments such as tunnels, plazas, industrial sites and outdoor supporting facilities.
Typical Applications
- Data centers and server rooms
- Telecom base stations and communication equipment rooms
- Industrial automation systems
- Hospitals and medical equipment
- Commercial buildings and office parks
- Transportation, tunnel and infrastructure projects
- Emergency backup power systems
